Executive Summary

This vulnerability is a path traversal issue in the Mobile Verification Toolkit (MVT) prior to version 2026.5.12. It occurs because the software does not properly sanitize file identifiers when processing iOS backups, which could allow an attacker to access files outside the intended directory.

Impact Analysis

The vulnerability could allow unauthorized access to files on a system by exploiting the path traversal flaw in iOS backup processing. This may lead to exposure of sensitive data or compromise of the device's forensic analysis integrity.

Mitigation Strategies

To mitigate this vulnerability, update the Mobile Verification Toolkit (MVT) to version 2026.5.12 or later, where the path traversal issue in iOS Backup processing has been patched.

Detection Guidance

This vulnerability affects the Mobile Verification Toolkit (MVT) commands related to iOS backup processing, specifically mvt-ios decrypt-backup and mvt-ios check-backup.

To detect the vulnerability, you can check the version of MVT installed on your system. Versions prior to 2026.5.12 are vulnerable.

Since the vulnerability involves path traversal via unsanitized fileID fields in iOS backups, you can use the following commands to analyze backups safely and verify if your MVT version is patched:

  • Run `mvt-ios check-backup` on your iOS backup to inspect the backup contents. This command was affected by the vulnerability but is now patched in version 2026.5.12.
  • Run `mvt-ios decrypt-backup` to decrypt the backup safely if you are using a patched version.

Ensure you have updated MVT to version 2026.5.12 or later to avoid exploitation. If you are running an older version, consider upgrading immediately.

Compliance Impact

The provided information does not specify any direct impact of this vulnerability on compliance with common standards and regulations such as GDPR or HIPAA.
